摘要
鉴于固定费用选址问题的一个重要局限是在运输成本的计算中,假设采用整车运输方式,其运输成本与考虑运输路径时的成本不同会影响选址决策.针对一个钢材销售企业的三级物流网络中的两级设施进行选址,采用多站式运输方式计算运输成本,问题为三级物流网络选址-路径问题.采用嵌入拉格朗日启发式算法的分枝定界方法来求解,并对该方法进行了实验测试,测试结果表明该方法是有效的.
An important limitation of the fixed charge location model is the assumption that full truckload quantities are shipped from a distribution center to a customer.The different location decision is made from the different cost of delivery.A particular three-layer steel product distribution network is investigated,in which two echelons of facilities are located.To make the location decision,the delivery cost of a multiple-stop route is calculated.A Lagrangian relaxation-based branch and bound algorithm is used to solve this location-routing problem.The numerical results for various size test problems are presented,and the results show the effectiveness of the method.
